There's one major minus in this games' subgenre, you need much more time to master the game controls. After the both Jet Set Radio and Future, this game has a little bit more deep mechanics (in some way), especially speed and jumping. I played alpha a lot, the first walkthrough of adventure mode takes more that 3,5 hours, the second one take less than 1 and half hour. Can't see how you'll try to complete the hardest challenges for the first time.
